ANOVA designs for estimating heritabilities of fecundity traits inHirudo medicinalis including batch size, the number of juveniles per cocoon, and juvenile weight. Accounting for reproduction mode of this species, different types of kinship were identified, which were taken into account in the ANOVA designs: juveniles from one batch and one cocoon were considered respectively full sibs and polyzygotic twins. Variation components were analyzed in the following kinship groups: for batch size, in full sibs; for the number of juveniles per cocoon, between sibships, full sins, and replicates; and for juvenile weight, in full sibs and polyzygotic twins. Using these designs, heritabilities of basic reproductive traits of H. medicinalis were obtained: for batch size, h
2 = 0.35–0.40, H
2 = 0.40–0.45; for the number of juveniles per cocoon, h
2 = 0.33–0.36, H
2 = 0.36–0.39; and for juvenile weight, h
2 = 0.40–0.44, H
2 = 0.44–0.48.

Abstract

ANOVA designs for estimating heritabilities of fecundity traits inHirudo medicinalis including batch size, the number of juveniles per cocoon, and juvenile weight. Accounting for reproduction mode of this species, different types of kinship were identified, which were taken into account in the ANOVA designs: juveniles from one batch and one cocoon were considered respectively full sibs and polyzygotic twins. Variation components were analyzed in the following kinship groups: for batch size, in full sibs; for the number of juveniles per cocoon, between sibships, full sins, and replicates; and for juvenile weight, in full sibs and polyzygotic twins. Using these designs, heritabilities of basic reproductive traits of H. medicinalis were obtained: for batch size, h
2 = 0.35–0.40, H
2 = 0.40–0.45; for the number of juveniles per cocoon, h
2 = 0.33–0.36, H
2 = 0.36–0.39; and for juvenile weight, h
2 = 0.40–0.44, H
2 = 0.44–0.48.
